I try to set up a depth dependent Temperature Gradient for a case in OpenFOAM with groovyBC.

FLOOR
{
type groovyBC;
variables "ypos=pos().y;";
valueExpression "(ypos-7300)*(-0.025)+273";
}

when I run the case, I get the following in the output of the first written timestep:

FLOOR
{
type groovyBC;
refValue nonuniform List<scalar>
283
(... here are 283 correct values);
refGradient uniform 0;
valueFraction uniform 1;
value nonuniform List<scalar>
283
(... here are the same 283 values);
valueExpression "(ypos-7300)*(-0.025)+273";
gradientExpression "0";
fractionExpression "1";
variables "ypos=pos().y;";
timelines (
);

why is it written in refValue and value? I use a Temperature reference Value and define it elsewhere, to calculate the density... But this one I don't need.

Then there is a further problem, no clue if it's connected...
The field phi gets a completly wrong number of points for the internal field and several nan. The field U gets the right number of points in the internal field but as well a lot of nan... Does someone have an idea about this?

Cheers,
Maike.
